and provide a road map for how far the united states will go in defense of israel. we will get insights to all of these challenges for president obama with the former ambassador to israel, martin indyk who joins us from washington where he is the vice president and director for foreign policy at the brookings institution. ambassador indyk, good to have you back on the program, sir. >> thanks, tavis, good to be with you. tavis: i guess the start is whether or not i have overstated the case. there are some who believe as i intimated a moment ago that the president's very presence in israel that's to say, our president, barack obama, signals to some there might be renewed vigor, renewed possibility for peace between the israelis and palestinians and there are many more others, perhaps, as i read, who think it's a false hope, that the expectations on this need to be tamped down. where does ambassador indyk stand? >> certainly the white house has been trying to tamp down those expectations, including the president himself.
